Scattering Junctions

Suppose now that we would like to draw a new signal flow graph, using wave quantities. The problem now is that in general, the wave variables corresponding to a particular WD 1-port are scaled by $ different$ port resistances. So how do we connect them?

We need to derive $ scattering$ $ equations$ ...indeed, whenever we have an impedance change (even an artficial one such as this), we expect relection and transmission.
